1. To ensure our membranes perform optimally, permeate flow rate and salt rejection rates are precisely calculated under rigorously tested standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) before undertaking any hot water disinfection process.
2. Be aware that the permeate flow range can vary by +/-15%, and the final water yield may further fluctuate due to
the involved heat treatment procedures.

ProshareRevolutionizing Reverse Osmosis: Our Team's Breakthrough
ProshareOur team at Proshare has pioneered a groundbreaking advancement in reverse osmosis membrane technology. By harnessing the transformative power of polymer interface nano-self-assembly, we have transcended traditional barriers in membrane development, introducing two revolutionary innovations that redefine performance and efficiency:
Ultra-Thin Separation Layer: With cutting-edge polymer interface nanotechnology, we have developed an incredibly thin separation layer, at least three times thinner than the conventional 100 nm polyamide films. This remarkable reduction in thickness boosts water flux, significantly enhancing both permeability and efficiency to unprecedented levels.
Enhanced Performance: The integration of nanoparticles with specialized hydrophilic polymers has led to groundbreaking achievements in the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance, setting new standards for performance.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation results in breakthroughs across four pivotal aspects:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification has enabled the formation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This pioneering technique surpasses the thickness uniformity and material diversity constraints inherent in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through precise optimization of the layer-by-layer self-assembly process, we have meticulously regulated the functional layer thickness, achieving an astonishing 3x reduction compared to traditional membranes. This strategic advancement results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking away from polyamide, our team employs advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials demonstrate superior oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (stabilizing within an extensive 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, engineered with a contact angle under 10° and reinforced by nanoparticles, effectively reduces organic fouling by an impressive 50%. This innovation extends chemical cleaning cycles from 3 to 6 months, slashing maintenance costs by 40% and ensuring long-term efficiency.
